13 Claims.

This invention relates to improvements in book binding and is directed more particularly to improvements in apparatus and methods for outtingoff and crimping or turning in the ends of bindings for books of the type shown and described in U. S. Letters Patent to Eden, No. 1,986,757, issued January 1, 1935.

The principal objects of the invention are directed to the provision of improvements in apparatus and methods for cutting off and crimping or turning in the ends of bindings which are formed from wire or the like to have rings which pass through the perforations of leaves of the books and are spaced apart by connecters.

Another object of the invention is the provision of an apparatus for cutting off and crimping or turning in the ends of the bindings.

Various other novel objects and advantages of the invention will be hereinafter more fully referred to in connection with the accompanying description of the preferred form of the invention, reference being had to the drawing wherein:

Fig. 3 is an enlarged elevational sectional view on the line 33 of Fig. 1;

Fig. 4 is a front elevational view of the apparatus shown in Fig. 3; a

Fig. 5 is a side elevational view of the crimping device shown in Fig. 3 taken at an opposite side thereof;

Fig. 6 is a plan view of the endmost portion of I a book with the binding therein to explain how it is acted upon by the crimper of the invention; Fig. 7 is an edge view of a book and binding showing the binding before it is cut off and crimped; and

Fig. 8 is a view similar to Fig. 7 showing the binding after it has been cut off and crimped in accordance with the invention.

Referring now to the drawing more in detail, the invention will be fully described.

A base 2 is provided in which is oscillatable and reciprocable a shaft 4 which carries the crimping mechanism. A rack 6 is movable in a plane transverse to the axis of shaft 4 and may be actuated by any suitable means. In the form of the invention shown, the rack 6 is operated by an armature 8 of a solenoid [0 supported by uprights I2 which are carried by the base 2.

The shaft 4 has a gear I4 associated therewith which is in engagement with the rack 6 whereby it is oscillated and a cam I6 on the end of shaft 4 formed with a cam groove I8. A cam follower 20 on a block 22 associated with the base brings about reciprocatory movements of the shaft as it is oscillated.

The outer end of the shaft 4 as shown in Figs. 3, 4. 5 and 6 carries a projection or horn 40 which in part provides the crimping and cutting off mechanism. The part 40 in the position shown is ready to receive the binding and it then rotates or oscillates counterclockwise from the position shown in Fig. 4 through an angle of approximately 180.

The shaft 4 is slotted longitudinally and it is cut away on a side thereof as shown at 30 in Fig. 6. A latch member 32 is disposed in the slot of the shaft 4 and has a forward detent portion 34, a lug portion 36 is disposed in the recess 30 and is arranged for rocking movements on a pin 38. The forward part 40 of the shaft 4 constituting the crimper is slotted transversely on its end as indicated by 42 to receive the binding. A cutting edge 44 is provided on the outer side of the part 40 adjacent slot 42 as shown in Figs. 4 and 5 which co-operates with a cutting edge 66 of a cutter 64 above the part 40.

The lower forward side of the detent 34 of the latch 32 is curved as shown in Fig. 3. The latch 32 is mounted for swinging movements and it is possible therefore in the position of the shaft shown in Fig. 3 to insert the binding in the slot 42 by pressing it against the detent. This causes the latch 32 to be elevated to expose the slot. When the binding is in the recess 42 the latch moves downwardly so that the binding is enclosed in said groove by the said latch detent. A spring 46 in a socket 48 acts on the rear end of the latch 32 and tends to hold it in the position shown in Fig. 3.

As the shaft 4 rotates counterclockwise from the position in Fig. 4 through an angle of approximately 180, a part 33 of the latch engages and rides onto a cam 50 disposed in a slot 52 in the lower side of the base which causes the inner end of the latch to be depressed, the outer end carrying the detent 34 to be elevated, to uncover slot 42 and permit the binding to be withdrawn from the slot 42. The rack 6 by being reciprocated in opposite directions causes the shaft 4 to oscillate in opposite directions, counterclockwise for a cutting and crimping operation and then clockwise.

An abutment 60 is disposed below the part 40 and this may be associated with the plate 62 secured to the underside of the base 2.

As disclosed in the patent to Eden, No. 1,986,757, a binding B usually of wire may consist of a plurality of rings or loops I0 which extend through openings I2 of the leaves of a book L. The ends of the rings iii are connected by longitudinal bars or spacers 14. In the binding of the book, the binding is usually longer than the book so as to extend beyond the edges thereof as shown in Figs. 6 and 7. It is to cut off the excess binding and crimp or turn in the end portion of the binding that the apparatus and method of this invention relates and it is accomplished in the following manner.

That bar 14' of the binding B which is outside that ring or loop 10' thereof which passes through the endmost perforation 12 of the book is inserted in the notch or groove 42 of the part 40. This is accomplished by pressing the bar 14' against detent 34. The book is held in a substantially horizontal plane, while the rack 6 is actuated to rotate the shaft 4 and crimper mechanism counterclockwise. As the shaft 4 is thus rotated the cutting edges 66 and 44 of the shear and of the part 40 co-operate to sever the binding near the outer end of bar 14 or at a point away from the last ring or loop 10'. As the said shaft 4 rotates the said bar of the binding is turned counterclockwise so that it is turned inwardly alongside of bar 14 extending from ring 10'.

As has been explained, during this counterclockwise oscillation of the shaft 4 it is moved rearwardly or axially to some extent by means of cam groove I8 and projection, (see Fig. 2). This is so that the bar 14 will not be brought over onto the next adjacent bar 14 connected to ring 10' but instead will be positioned at a side thereof as shown in Fig. 8.

When the shaft .4 has been oscillated through its angle of movement to cut off the binding and crimp or turn the bar 14 inwardly, the portion 33 of the latch 32 will bring up against the cam 5|] whereby the outer end or detents 34 of the latch 32 is elevated to uncover notch 42 whereupon the binding is released so the book may be pulled forwardly.

It will be noted that by means of the method and apparatus that the binding is cut and crimped simultaneously in a simple and efficient manner and is accomplished by the novel means described.

While I have described the invention in great detail and with respect to a preferred form thereof, it is not desired to be limited thereto since many changes and modifications may be made therein without departing fromthe spirit and scope of the invention.
